AC To DC Power Supply

What is AC-DC power supply?

The AC-DC power supply converts an AC voltage into a DC voltage, such as a charging adapter for a mobile terminal. AC power is supplied to general homes and offices, but most electronic circuits built into electrical appliances operate on DC voltages such as 5V and 12V. Therefore, AC (alternating current) must be converted to DC (direct current), which is essential for electrical products.

AC To DC Power Supply

Some electric appliances, such as incandescent light bulbs and motor equipment, are driven by AC voltage and do not require AC-DC conversion. However, recently, due to heightened awareness of energy saving and power saving, incandescent light bulbs are being replaced by LED lights driven by DC voltage, and motor equipment uses a control circuit (microcomputer circuit, etc.) that operates by DC voltage for more power efficiency. Good inverter control is becoming popular. Therefore, it can be said that the need for AC-DC power supplies is increasing.
